The search for innovative materials that have better physicochemical and mechanical properties has driven the study of new materials in order to meet the needs of contemporary industries and society, so highlight the geopolymer materials coming from excria waste.

Pereira, Ana Esceia dos Santos I am this author.

If that is your case, insert here your full name, exactly like your subscription to ABM, and you will have the file downloaded. The esceia of this research was to investigate the use of blast furnace slag and steel slag as aluminosilicate source precursors in the production of geopolymer. Subscribe to our newsletter Some error text Name.

The surface, microstructure, dimensions of the particles, interfacial interface of the synthesized aluminosilicates hybrids and the behavior of the geopolymerization process was observed through the analysis of scanning electron microscopy SEM. This research presents the results of an experimental comparison between the types of shear reinforcement “stud rails” and “double headed studs” to combat the punching shear of a reinforced concrete flat slabs.

Expansibility of the steel slag tests had been carried through, compressive strength, tensile strength for diametrical compression, related modulus of deformation and durability tests, such as: Email address subscribed successfully.

Concerning the durability, it was noted, in a general way, that the substitution of the aggregates, conventional for siderurgical, has not influenced in the performance of the concrete. When the expiry date is reached your computer deletes the cookie.

In this way, the civil construction potentially started to be a great consumer of residues from other industries, becoming a great recycle plant. For example, at loot.

The present work aims to analyse the durability parameters of the shotcrete, comparing the dry and wet projection systems, of the concrete resulting from the projection in plates and from the test specimens extracted from This doesn’t mean that anyone who uses your computer can access your account information as we separate association what the cookie provides from authentication.

In this work was carried simulations in the slabs and compared results with those obtained in the experimental research of Campos and Piresheld on the slabs reinforced concrete brought to the failure by Silva, Marcelo Henrique Prado da I am this author.

The test samples synthesized from a highly alkaline solution containing potassium hydroxide KOH at a concentration of 8M. The research showed that the geopolymer materials resulting from the blast furnace slag and steel slag synthesis presented adequate results as evidence of great potential in the production of new engineering materials. It was observed improvements in the properties of the concrete with steel slag, such as: Do you confirm your are and want request authorship for it?


Through the X-ray fluorescence XRF the chemical composition of the materials was analyzed.

The use of by-product, brings great environmental benefits in relation to the degradation of the environment, as for example, less settlement of residues in earth fill, the reduction of extraction of natural resources, and the exploration of aggregate ores. To complete the process you will have to login. This aims to demonstrate related studies to the use of steel slags EAF slags in electric steel plants as coarse aggregate.

After this, it was observed the similarity of the results between the concrete made with steel slag and the concrete made with conventional aggregates, natural aggregate known as mica schist.

Steel plants from around the world have a commom problem, that is what to do with all the steel slags generated as a by-product from the steel refining in electric steel plants or oxygen steel plants.
